This is a great add-on, I use it and personally recommend to all. Just by looking at a page, you will be able to see all dead links.
1. After You Install The Below Given Scripts Check if Greasemoney is Enabled (Enabled by Default).
2. Now when you visit a forum/site go to add-on Greasemonkey => Manage User Scripts => Add.
3. The forum will be added in Greasemonkey and you will be able to see if the links are dead or not.
THIS ADD-ON IS FOR FIREFOX ONLY !!!!!
